200 What is the primary function of the light reactions of photosynthesis? A).to produce energy-rich glucose from carbon dioxide and water B).to produce ATP and NADPH C).to produce NADPH used in respiration D).to convert light energy to the chemical energy of PGAL B. To produce ATP and NADPH

300 Oxygen is released by the A).Light reaction of photosynthesis B).Dark reaction of photosynthesis C).Formation of ATP from ADP D).”Excited” electrons in the chlorophyll molecule E).Splitting of the 6-carbon sugar A. Light reactions of Ps

300 In the absence of oxygen, yeast cells can obtain energy by fermentation, resulting in the production of A).ATP, CO2, and ethanol (ethyl alcohol) B).ATP, CO2, and lactate C).ATP, NADH, and pyruvate D).ATP, pyruvate, and oxygen E).ATP, pyruvate, and acetyl CoA A.

400 C6H12O6 + 6O2  6H2O + 6CO2 + 38 ATP The process shown is… A. Reduction and is endergonic B. Reduction and is exergonic C. Oxidation and is endergonic D. Oxidation and is exergonic E. Neither oxidation nor reduction but must be endergonic because energy must be added to the reaction to get it started. D. Energy is released and carbon loses hydrogen atoms in oxidation

A).blue and violet B).green and yellow C).red and yellow D).blue, green, and red E).green, blue, and violet C. Red and yellow

300 How does carbon dioxide enter the leaf? A).through the chloroplasts B).through the mesophyll C).through the thylakoids D).through the stomata E).through the vascular system D

400 CAM plants keep there stomates closed during the daytime to reduce excess water loss. They can do this because they… A. Can fix CO2 into sugars in the mesophyll cells B. Can use photosystems I and II at night C. Modify rubisco so it does not bind with oxygen D. Can incorporate CO2 into organic acids at night E. Have lenticels instead of stomates D
